In Wisconsin, the general rule is that breweries aren't allowed to give anything away except tasters less than 3oz. We'll ignore, for the moment, reality and just all agree that this is the law. This means that beer fests, etc. have to pay for the kegs that the breweries then serve to attendees.
There are two exceptions to this rule, codified in Wisconsin Statute Section 125.33(2):
"(h) [breweries may] contribute money or other things of value [read: kegs] to or for the benefit of a nonprofit corporation, exempt under section 501(c)(3) of the internal revenue code ..., which is conducting festivals of limited duration ..."
--- So (h) basically allows breweries to donate kegs to festivals held by 501(c)(3) nonprofits, this seems reasonable, as a public policy we want to encourage charitable giving and fundraising by these entities, so we carve out a narrow exception that allows breweries to donate beer, that's all fine and dandy
Here's the second exception:
"(hm) [breweries may] contribute money or other things of value to or for a nonprofit corporation which conducts an autumn ethnic festival of limited duration in a 2nd class city that had a population in 1986 of at least 49,000 but less than 50,000 ..."
--- Does that seem really specific to you? It does to me. How many cities in Wisconsin do you think had a population between 49,000 and 50,000 in 1986??? Off the top of my head, I can think of one: La Crosse, WI. So, unless I'm mistaken (and I don't think I am - how many other cities of this size have an "autumn ethnic festival" worthy of carving out an exception for?) this exception allows breweries to donate beer to the La Crosse Oktoberfest (an "autumn ethnic festival"). All the other festivals and Oktoberfests? Screw you, you have to pay. I don't get why we make an exception for this one? Why the protectionism? More importantly, why go through such tortured specificity to get to it? Why not just say "La Crosse, WI"? Why say "a 2nd class city (HA!) that had a population in 1986 (why 1986?) of at least 49,000 but less than 50,000"? Do any other cities even fit this description? The only ones I can find that are close are Oshkosh, Sheboygan, and Wauwatosa. Presumably, if these others do fit that criteria, they could start "autumn ethnic festivals" (read: Oktoberfests) and breweries could donate beer to them.
